OpenSSL http://www.openssl.org/source/license.html
Uses an Original BSD-style license with an announement clause that
makes it "incompatible" with GPL. You are not allowed to ship binaries
that link with OpenSSL that includes GPL code (unless that specific
GPL code includes an exception for OpenSSL - a habit that is growing
more and more common). If OpenSSL's licensing is a problem for you,
consider using GnuTLS instead.

Uses the LGPL[3] license. If this is a problem for you, consider using
OpenSSL instead. Also note that GnuTLS itself depends on and uses
other libs (libgcrypt and libgpg-error) and they too are LGPL- or
GPL-licensed.

GSSAPI
MIT Kerberos http://web.mit.edu/kerberos/www/dist/
While nothing in particular says that a GSS/Kerberos5 library must use
any particular license, the one I've used (Heimdal) is Original BSD-
licensed with the announcement clause.
(May be used for GSS support) MIT licensed, that shouldn't collide
with any other parts.
Heimdal http://www.pdc.kth.se/heimdal/
(May be used for GSS support) Heimdal is Original BSD licensed with
the announcement clause.
GNU GSS http://www.gnu.org/software/gss/
(May be used for GSS support) GNU GSS is GPL licensed. Note that you
may not distribute binary curl packages that uses this if you build
curl to also link and use any Original BSD licensed libraries!
fbopenssl
Unclear license. Based on its name, I assume that it uses the OpenSSL
license and thus shares the same issues as described for OpenSSL
above.

libidn http://www.gnu.org/licenses/lgpl.html
Uses the GNU Lesser General Public License. LGPL is a variation of GPL
with slightly less aggressive "copyleft". This license requires more
requirements to be met when distributing binaries, see the license for
details. Also note that if you distribute a binary that includes this
library, you must also include the full LGPL license text. Please
properly point out what parts of the distributed package that the
license addresses.

OpenLDAP http://www.openldap.org/software/release/license.html
Uses a Modified BSD-style license. Since libcurl uses OpenLDAP as a
shared library only, I have not heard of anyone that ships OpenLDAP
linked with libcurl in an app.
